WILLIAM A. LORENZ, OF HARTFORD, CONNECTICUT, ASSIGNOR, BY MESNE ASSIGN- .MENTS, TO THE NOISELESS TYPEWRITER COMPANY, OF MIDDLETOWN, CONNECTI- OUT, A CORPORATION OF CONNECTICUT.

TYPE-WRITING MACHINE.

To all whiz/mt it may concern:

Be lb liIlOWll that l, W JLIJAM A. Lonnnz, a citizen of the United .States, residing at .llartford, in the county of Hartford and State o-l. Connecticut, have invented certain new and. useful lm 'n'ovcments in Typeriting Machines, of which the following isa full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. i

i This invention relates to ty 'iewriting machines and with regard to the more specific features thereof, to improved type actions therefor. i

One of the objects of the present invention is to provide a practical and ellicient type action for typewriting machines.

Another object isto provide a silently acting type action with an easy dip to the operating key and a prompt return to normal position.

Another object is to provide a type action inwhich rebounding of the movable parts will be eliminated.

Another object is to provide a simple form of type action which will be cheap to manufacture and easy to install.

A further object to provide an improved form of'universal bar mechanism adapted-to be used with the present form of type action although not limited thereto.

A further object-is to provide sa light but substantial carriage mechanisn'i.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinaftcrset forth, and the scope of the application of which. will be indicated in the following claims.

*In the accompanying drawings, wherein are shown several oi. various possible embodiments ot' the present invention, Figure l ism-sectional view showing one/form of type action in normal position; Fig. 2 is a similar view' showing thetype-bar in actuated position; Fig. 3 is an enlarged view of a portion of Fig. 2-; Fig. 4 isa-pla11 View of the part shown i-n.Fig. 3; Fig. 5 is a Specification of Letters Patent.

detail sectional view; Fig. (3 a modification showing one form of arresting means; lug, .1, is. a partial sectional view showing a further modification;..Fig. 8. is. a view similar to Fig (3, with the action in extended posltiou; and Fig. 9 isa plan view showing the improved form of. platch carriage.

Similar reference characters refer to similar parts, throughout the several views of the drawings.

While the present invention is illustrated and describedwith reference to that form of typewriting machines known as the noiseless typewriterj it is, oat-course, to be understood that various features herein described and claimed, while 'iarticularly adaptable to pressure-operated:machines. may be applied to other iori'ns of type ac tlous. and in other connectioi'is as well.

Referring now to these drawings in detail, and particularly I igs. land 2, 1 represents a platen or paper-roller mounted upon a rod 2, and, in the present case, being prelerably provided with alfiat metallic platen 3 adapted to receive the compressive or squeezing action exerted upon the paper by type l carried by a.typc member a. This type member is mounted upon the forward end of a reciprocating type-carrier 6, having rcarv'ardly extending guide legs, the upper one being the longer, and in the form herein shown is provided with a normal or central type with upper and lower case type adjacent thereto. The uppcr and lower parts of the type member 5 are provided With forwardly projecting type-protecting means 7 which extends slightly in advance of the face of the type In order that the purpose of these type-protecting members may be the more readily understood, it may be explained that in the noiseless typewriter, as well as some other makes, the ty ie-carriers arearranged radially to the printing point; those type-carriers at the extreme outer edge of, the type segment bea vertical plane disposed substantially at an angle of .45. to the printing line. Now, should one type-carrier be actuated by one hand and moved. to the printing position while a second. type action at the opposite side of the segment is still at the printing [position, not having been released by the other hand, it willbe seen that the type members will contact with one another, to the probable injury of the last actuated 'type action.

' Therefore, if the type members are provided prevent a tilting motion of the type-carrier when actuated. The lower part of the typecarrier may be cutaway, as shownin the drawings, to avoid unnecessary friction, if so desired. In order to prevent the typebar from tilting sidewise when in extended position, as shown in Fig. 2, a comb member 11 projects upwardly fromthe bed-plate 9 and engages the sides of the type-carrier in the manner shown incross-section in Fig. 5. The type-carrier 6 is connected with an actuating key-lever 12 by intermediate mechanism including a toggle cam link 13, which, with an upwardly swinging oscillatory cam member 14,-is adapted to form a toggle, shown in extended position in Fig. 2, for positively limiting the movement of the type-carrier, thereby creating a normal printing plane, relatively to which the platen is movable by mechanism such as shown for example in Patent No. 879,107, dated February 11, 1908, to Kidder and Sponsel. This toggle cam member 14' is pivotally mounted at 15 on an adjustable cam block 16 secured to the front wall of the machine. This cam blockmay be adusted in the direction of the path of travel of the type-carrier by means of set screws tel-mines the adjusted position.

17 and 18, the former clamping the adjustmg block to the frame, while the latter deupper part of the cam block 16 is pivotally mounted a bell-crank lever or toggle-actuat-v ing member 19, the shorter arm'of which sconnected by-means of an adjustable pullvgire 20 with "the key-lever 12, while the longer arm carriesya roller 21 adapted to form a rolling connection with the oscillatory cam member 14 by engaging a cam slot 22 therein. This cam slot 22 is gradually curved through the larger part ofits length and terminates near one end in a' sharply defiebted cam portion indicated at 23. This cam slot is of such a configura- .-,,tion as t6, caus .,a gradually increasing rate ;of movement toward the platen during the On the first-part of the movement of the key-lever and a gradually decreasing rate of movement, terminating in a compressive or toward and from the platen is positivelycontrolled. This cam slot 22 is also provided at each end with an extended portion known as a cam dwell, the curvature of the cam at these points being concentric with an arc struck from the pivotal point of the bell-crank lever as a center. In Fig. 3 the type action is shown in extended position in. full lines, the dotted position of the bellcrank lever 19 denoting the extent of additional movement into the cam dwell permitted thispart and also the key-lever without in any way alfecting the movement of the type-carrier.

Referring to Fig. 4*. of the drawing, it will be seen that the adjusting block 16 is bifurcated at its forward end and holds the oscillatory cam member 14 therebetween. This cam member has a rearwardly projecting portion or horn 2 1- which is adapted closely to it between the sides of the block 16, whereby a tilting motion of the camis counterbalance the weight, of the pull-wire 20 and the key-lever 12, when returning to normal position. In this manner a more rapid return of the parts to normal position is attained and also the possibility of the type carrier or other parts of the actuating mechanism rebounding, as might ocour in mechanisms where the oscillatory cam member swings upwardly when returning to normal position, is eliminated.

The key-lever 12 is pivotally mounted upona transversely disposed shaft 25, to

which is also pivotally supported a universal bar 26 by means of .rearwardly extending arms 27. S rings 28' and 28 en- -gage,respectively, t e key-lever and the engaging a pad 33 ontheupper'surface of a the universal bar 26, thereby silently to arrest the upward movement of the bar when returning to normal position.

By pivota'lly mounting the universal bar and key-lever upon the same pivot the friction between the surfaces of the key-levers which oscillate and the universal bar contacting therewith, which reciprocates, is eliminated.

In order that the actuating mechanism interposed between the type-carrier and keylever may be silently arrested'upon its return n'iovement, an abutment 34 provided with silencing means such as a pad 35 is adapted to be engaged by a projecting arm 36 on the oscillatory cam member whereby this part will return to normal position without impact or concussion.

' 'lhe operation of this modification, it is thought, may be understood from the above description, but it will, nevertheless, be stated, in brief, as follows: When a keylever is actuated, it not only depresses the universal bar 26, thereby to actuate the escapement mechanism, not herein shown, and space the carriage in the usual manner, but also draws the pull-wire20 downwardly, thereby oscillating the bell-crank lever 19 to cause the roller 20 carried thereby to traverse the cam slot in the cam member 14 and move the type-carrier forward to the printing position. When the toggle formed by the cam member and link 13 is in extended position, the type will have reached the normal printing plane. It is, of course, to be understood that the platen and the typemembers are movable relatively to each other, in order that, when manifolding, the outer sheet may be disposed in the normal printing plane.

Referring now, briefly to Fig. 6, the means for silently arresting the return of the actuating mechanism to normal position comprises a stop member or pad 37' position'edupon the movable link 13 and which is adapted to be engaged by a projecting.

- lug 38 on the oscillatory cam member 14. This will not only silently arrest the parts on return to normal position, but also prevents the rear end of the type-carrier from riding upwardly on its return movement, as a downward pressure will be exerted upon the pad 37 by the cam member when returning to norinalposition. This same mechanism is shown in actuated position in Fig. 8, and otherwise is substantially the same as the action shown in Fig. 1.

In Fig. 7 is shown a somewhat similar type action, in' which the silencing pad'is disposed on a forwardly projecting lug 39 secured to'the frame of the machine. A heel orthe like 40' carried by the link 13 is adapted to engage thispad in the manner herein shown. I

F g- T9 is,v hown 1n plan' v ew'th platen-carriage, in which the platen 3 secured to end plates 41 lies closely adjacent the platen roller or paper roller 1. By securing the platen in this manner, with the coiicaved face lying adjacent the platenroller, there will. be no tendency for the platen to move upwardly ordownwardly from a normal position when struck slightly off center, as illustrated in Fig. 8, the dotted line representing the center of a normal impression, while the type therein shown designates a period normally striking below the center of the printing line. It is thus seen that this invention is adapted to accomplish, among others, the objects above set forth in a practical and ellicieiit manner.

As many changes could be made in the above construction and many apparently widely dilierent embodiments of this invenand specific features of the invention lierein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
